+[note There are portability issues with this template - in particular the `hash` template
+might not actually be defined inside namespace std::tr1, making user-defined specializations
+of the template non-portable.  For example Visual C++ 2010 defines `hash` in namespace `std`
+and then imports this into `std::tr1` with a using declaration.]
